Let's divide 26192997 by 581
The aim is to understand the frequency of 581 in 26192997.

On to step 1:
The number 581 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 581

Advancing to step 2:
When dividing 26 by 581, we get 0 with a remainder of 26.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 26 to get 26.
Append the next digit (1) from the dividend to 26 and continue with: 261 / 581

Advancing to step 3:
581 goes into 261 0 times with a remainder of 261.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 261 to get 261.
Bring next digit (9) of the dividend behind the 261 and repeat the process: 2619 / 581

Moving on to step 4:
581 can be fit into 2619 4 times, resulting in a remainder of 295.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 2324 away from 2619, we end up with 295.
Append the next digit (2) from the dividend to 295 and continue with: 2952 / 581

Step 5:
2952 divided by 581 is 5 with a remainder of 47.
Put 5 as the next digit of the answer. 
Result so far: 45.0
If we subtract 2905 from 2952, we get 47.
Append the next digit (9) from the dividend to 47 and continue with: 479 / 581

Going ahead to step 6:
581 can be fit into 479 0 times, resulting in a remainder of 479.
Use 0 as the next digit of our solution. 
Result so far: 450.0
The remainder is 479 after subtracting 0 from 479.
Fetch the next digit (9) from the dividend, attach it to 479 and continue: 4799 / 581

Going ahead to step 7:
581 goes into 4799 8 times with a remainder of 151.
Write down 8 as next digit of the result. 
Result so far: 4508.0
If we take 4648 away from 4799, we end up with 151.
Include the next digit (7) from the dividend after 151, then repeat: 1517 / 581

Step 8:
If we divide 1517 by 581, we get 2 and a remainder of 355.
The number 2 becomes the next digit in our result. 
Result so far: 45082.0
If we subtract 1162 from 1517, we get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Advancing to step 9:
3550 divided by 581 is 6 with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 45082.6
The remainder is 64 after subtracting 3486 from 3550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
If we divide 640 by 581, we get 1 and a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 45082.61
If we take 581 away from 640, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 11:
581 goes into 590 1 times with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 45082.611
The remainder is 9 after subtracting 581 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final result is 45082.611 with a remainder of 0.0009.
